ANDREW S. BROWN, OF NEIV YORK, N. Y.

OPENER OR CLOSER FOR SKYLIGHTS.

SPECIFICATION forming part of Letters Patent No. 618,053, dated January24, 1899.

Application filed December 4, 1897. Serial No. 660,802. (No model.)

To all whom it may concern:

Be it known that 1, ANDREW S. BROWN, a citizen of the United States,residing at New York, (Brooklyn,) in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Opener orClosers for Skylights, &c., of which the following is a full andcomplete specification, such as will enable those skilled in the art towhich it appertains to make and use the same.

This invention relates to mechanism for opening and closing pivoted orhinged skylights; and it has for its object to provide a simple andimproved mechanism of this class which will be compact in construction,effective in operation, and adapted to be mounted in close relation tothe outer wall of the skylight-frame, so that it can be convenientlyused for ships skylights and in analogous positions and arrangements.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by the same letters of reference ineach of the views, and in which- Figure 1 is an elevation, partly insection, showing my improved mechanism in position. Fig. 2 is a verticaltransverse sectional view through the skylight-frame, the mechanismbeing shown in side elevation. Fig. 3 is a de tail transverse sectionalview through the pivoted arm which carries the skylight. Fig. 4 is avertical sectional view through the skylight-frame, showing in sideelevation a modified form of myimproved skylight mechanism adapted forgeneral application and use other than in connection with shipsskylights; and Fig. 5 is an end elevation of the construction shown inFig. 4.

Referring to the drawings, A designates the skylight-frame, and B thepivoted or hinged skylight. At a suitable point near the outer or freeend of the skylight B is connected by a pivot-ed or hinged joint, as atc, an arm O, which swings or depends downwardly from the skylight. Thisarm embodies two parallel side bars 0 0 which embody longitudinalgrooves, as at 0 in their opposite faces, the bottom of one of saidgrooves being provided with teeth, and c forming a rack, as shown.

In the arms 0, between its side rods 0 and a is arranged a pinion D, theperiphery of which travels in the grooves c of the respective bars 0 cand engages the longitudinal rack 0 The pinion is thus retained orhoused within the arm 0 by means of the receivinggrooves in therespective side bars of the same and is held in connection with said armand against lateral displacement. ion D is carried upon a shaft E,transversely arranged with relation to the arm C and bearing in suitablebrackets F F, projecting from the skylight-casing A. This shaft carriesa vertical bevel-gear Gr, meshing with a corresponding horizontalbevel-gear H, arranged at the top end of a rotary operating-arm I.

To provide for the separation of the different parts, the grooves of theside bars of the arm 0 terminate in a bifurcated pivotal top end, asshown in dotted lines at c in Fig. 2 and in Fig. 1, whereby when thepivot c of said arm is disconnected the arm may be disengaged from theinclosed gear-pinion D. The arm is preferably of loop shape, as shown.The rotary operating-arm I is supported upon a bearing-pin f, projectingdownwardly from the bracket F and through the bevel-gear H, the gearbeing adapted to turn upon this pin. (See Fig. 1.)

A lower bearing for the operating-arm I is provided by a cylindricalcollar J, embracing said arm and carried upon a suitable bracket K,projectingfrom the skylight-casing. Said collar may be provided withset-screws, as at j, by the adjustment of which the arm I may be securedin fixed position to maintain the skylight and the operating mechanismin their adjustment. A handle 1' may be provided at the lower end of thearm I, by which it may be rotated, or any suitable means for connectionof an operating device may be employed.

It will be understood from the foregoing de scription and by referenceto the drawings that the mechanism will maintain a compact position nearand with relation to the wall of the casing of the skylight and that itrequires no rods or arms or operating devices extending downwardly amaterial distance, by means of which improved construction andarrangement the mechanism is especially adapted for convenient use uponships skylights and in similar positions and arrange- The gear-pim mentswhere the space is contracted and where projecting devices would be aserious obstruction.

It will be noted that the pivoted arm (J in the modified formillustrated in Figs. 4 and 5 is the same in its general construction asthe form of said arm illustrated in Figs. 2 and 8, having the grooves inits opposite inner faces and the rack in the bottom of one of saidgrooves, and also that the shaft E in the modified form carries thepinion operating in said grooves and rack in the arm. The only essentialvariation in construction and arrangement between the form illustratedin Figs. 1, 2, and 3 and the modified form illustrated in Figs. 4 and 5consists in the operatin g mechanism which is connected with the shaft Eand which is above described.

Having fully described my invention, I claim as new and desire to securebyLetters Patent 1. The combination with the swinging sash, of an armpivotally secured thereto, said arm comprising two parallel bars havingoppositely-situated grooves in their inner faces, a rack in the bottomof one of said grooves, a pinion between said'arms, extending into saidgrooves, and inter-meshing with said rack, and means for operating saidpinion.

2. An improved skylight mechanism, comprising, in combination with theskylight, a pivoted or hinged arm depending therefrom and embodying sidebars having grooves in their opposite faces and provided with teethforminga rack-bar within one of said grooves, a transversely-mountedshaft carrying a pinion operating between the side bars of said arm andwithin the grooves thereof, gear mechanism carried by'said shaft, gearmechanism meshing with the mechanism upon the shaft and operated by adownwardly-projecting rotary rod or arm, and adjusting mechanismengaging said rotary rod or arm to lock it in adjusted position,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 2d day of December,1897.
